Combining Co-operative Diversity in Wireless Communication
Abstract: Wireless devices cannot employ Multiple Input Multiple Output (MIMO) due to hardware or size limitation. Wireless device should replicate their single antenna virtually to act like MIMO system for better performance. This process is possible through a new system known as co-operative communication. In this system, the terminal or nodes combined to transmit the signals to follow an antenna array and form the diversity. Diversity is nothing but transfer of …

A Review on Wi-Vi Technology
Abstract: Wi-Vi is a new emerging technology that captures moving objects behind a wall or obstacle. Previous attempts used array of spaced antennas to track the moving objects through walls. This would be very expensive and bulky. So, in its place Wi-Vi is used which uses only one receiver. Wi-Vi technology is similar to radar and sonar imaging. But Wi-Vi uses very low power Wi-Fi signals for the transmission. The Wi-Fi …
